Delete your account
How to ask for your Smart Meter account and the data held about you to be deleted.
Last updated: 5 November 2026
This page covers the Smart Meter app and service, published by Lockwood Technology Limited. You can delete your account in the app, or make a request from here without opening the app.
Delete your account in the app
- Open Smart Meter and sign in.
- Tap the Account tab (bottom bar, right).
- Tap Settings.
- Scroll to the bottom. Under Account, tap Delete account.
- Read the Delete account screen and tap Delete my account.
- In the dialog "Delete your account?", tap Delete my account.
- The app signs out and the sign-in page says "Your account has been deleted."
Your sessions and push devices end at once. The rest follows the table below.
How to request deletion
- Email info@lockwood.co.tz with the subject "Account deletion request", or call +255 655 128 012.
- Give the phone number you sign in with and your meter number, which is on the sticker. Do not send your PIN or a token.
- Say whether you want the whole account closed or only some data deleted.
- To prove the number is yours, we send a code to it by SMS and ask you to read it back to us.
- We answer within 30 days and send you an SMS when the deletion is done.
What is deleted, and what we must keep
| Data | What happens | When |
|---|---|---|
| Your name, phone number, language, app lock PIN and optional ID digits on your account | Deleted | Within 30 days |
| Sign-in sessions and device push tokens | Deleted | As soon as we confirm the request |
| People you share a meter with, and your access to shared meters | Deleted | Within 30 days |
| Settings and alert choices | Deleted | Within 30 days |
| Copies of the above in backups | Deleted as the backups expire | Within 90 days |
| Usage readings | Kept with the meter, which stays with the unit | Two years |
| Technical logs | Deleted automatically | Within 30 days |
| Purchases, tokens and the audit record, which may include your name and paying number as they were at the time | Kept, and used only for reconciliation, disputes and legal duties | For as long as the service runs |
Before you request closure
- Your meter belongs to the unit, so closing your account does not disconnect it, and any credit stays on the meter.
- Use any token you have not entered yet. You will not be able to see it in the app afterwards.
- If you still live in the unit, you can buy electricity through your building manager. To use the app again, your manager has to add your number again.
- If you are waiting for a refund, tell us in your request, so we can finish it first.
Deleting only part of your data
If you want to keep your account, list what you want deleted. We will delete what we are not required to keep, and tell you plainly what we cannot delete and why. People you share a meter with can also be removed in the app. For the full picture, see the Privacy policy.
